| HHC. from EFC. X7625B EFC3/T3.4.28. SEQUENCE STARTER MOTOR. This appeared to work quite normally and nicely on the teazer current, but when on the main current there appears to be an abnormal friction in the plain bearing as this heats up. At least we think this is the reason, but in case there is anything wrong with the armature we would like to have this temporarily removed so that we may do a test on it. The motor is being handed back to the Shop. EFC. | ||
